		<h1>Upgrading from 1.2 to 1.3</h1>

		<p class="important">
			<strong>Note:</strong> The instructions on this page assume you are
			running version 1.2. If you have not upgraded to that version please
			do so first.
		</p>


		<p>Before performing an update you should take your site offline
			by replacing the index.php file with a static one.</p>


		<h2>Step 1: Update your CodeIgniter files</h2>

		<p>Replace the following directories in your "system" folder with
			the new versions:</p>

		<p class="important">
			<strong>Note:</strong> If you have any custom developed files in
			these folders please make copies of them first.
		</p>

		<ul>
			<li>application/<strong>models</strong>/&nbsp;&nbsp; (new for
				1.3)
			</li>
			<li>codeigniter&nbsp;&nbsp; (new for 1.3)</li>
			<li>drivers</li>
			<li>helpers</li>
			<li>init</li>
			<li>language</li>
			<li>libraries</li>
			<li>plugins</li>
			<li>scaffolding</li>
		</ul>


		<h2>Step 2: Update your error files</h2>

		<p>
			Version 1.3 contains two new error templates located in
			<dfn>application/errors</dfn>
			, and for naming consistency the other error templates have been
			renamed.
		</p>

		<p>
			If you <strong>have not</strong> customized any of the error
			templates simply replace this folder:
		</p>

		<ul>
			<li>application/errors/</li>
		</ul>

		<p>
			If you <strong>have</strong> customized your error templates, rename
			them as follows:
		</p>


		<ul>
			<li>404.php&nbsp;&nbsp; =&nbsp; error_404.php</li>
			<li>error.php&nbsp;&nbsp; =&nbsp; error_general.php</li>
			<li>error_db.php&nbsp;&nbsp; (new)</li>
			<li>error_php.php&nbsp;&nbsp; (new)</li>
		</ul>


		<h2>Step 3: Update your index.php file</h2>

		<p>
			Please open your main
			<dfn>index.php</dfn>
			file (located at your root). At the very bottom of the file, change
			this:
		</p>

		<code>require_once BASEPATH.'libraries/Front_controller'.EXT;</code>

		<p>To this:</p>

		<code>require_once BASEPATH.'codeigniter/CodeIgniter'.EXT;</code>


		<h2>Step 4: Update your config.php file</h2>

		<p>
			Open your
			<dfn>application/config/config.php</dfn>
			file and add these new items:
		</p>

		<pre>
/*
|------------------------------------------------
| URL suffix
|------------------------------------------------
|
| This option allows you to add a suffix to all URLs.
| For example, if a URL is this:
|
| example.com/index.php/products/view/shoes
|
| You can optionally add a suffix, like ".html",
| making the page appear to be of a certain type:
|
| example.com/index.php/products/view/shoes.html
|
*/
$config['url_suffix'] = "";


/*
|------------------------------------------------
| Enable Query Strings
|------------------------------------------------
|
| By default CodeIgniter uses search-engine and
| human-friendly segment based URLs:
|
| example.com/who/what/where/
|
| You can optionally enable standard query string
| based URLs:
|
| example.com?who=me&what=something&where=here
|
| Options are: TRUE or FALSE (boolean)
|
| The two other items let you set the query string "words"
| that will invoke your controllers and functions:
| example.com/index.php?c=controller&m=function
|
*/
$config['enable_query_strings'] = FALSE;
$config['controller_trigger'] = 'c';
$config['function_trigger'] = 'm';
</pre>


		<h2>Step 5: Update your database.php file</h2>

		<p>
			Open your
			<dfn>application/config/database.php</dfn>
			file and add these new items:
		</p>

		<pre>
$db['default']['dbprefix'] = "";
$db['default']['active_r'] = TRUE;
</pre>


		<h2>Step 6: Update your user guide</h2>

		<p>Please also replace your local copy of the user guide with the
			new version.</p>
